The DataRowCollection is a major component of the DataTable. While the DataColumnCollection defines the schema of the table, the DataRowCollection contains the actual data for the table, where each DataRow in the DataRowCollection represents a single row.

You can call the Add and Remove methods to insert and delete DataRow objects from the DataRowCollection. You can also call the Find method to search for DataRow objects that contain specific values in primary key columns, and the Contains method to search character-based data for single words or phrases.
